Specification of Letters Patent.

Patented Oct. 10, 1916.

Application filed January 2, 1915. Serial No. 7.

To all whom it may concern Be it known that I, ORIN D; BUsHA, a citizen of the United States, residing at Cleveland, .in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Ambulances, of which the following is a full, clear, and exact description.

This improvement in ambulances relates to the means for supporting the cot or stretcher in the ambulance body; the object being to so support said cot that attendants may easily and conveniently put the cot into the ambulance or take it from the ambulance while a patient is on the same, and without danger of jarring the patient.

This invention consists in the construction and combination of parts shown in the drawing and hereinafter described and pointed out definitely in the appended claims.

In the drawing Figure 1 is a sectional plan view of the ambulance body and the cot therein; Fig. 2 is a plan view of the cot and its supporting mechanism; Fig. 3 is a side elevation of said cot and its supporting mechanism; Fig. 4 is a rear end yelevation of said cot and supporting mechanism and the adjacent parts of the ambulance pocket; Fig. 5 is a sectional end view of certain parts, the section being in the plane indicated by line 5-5 on Fig. 3;`Fig. 6 is a front elevation of the cot and its supporting mechanism; Fig. 7 is a sectional side elevation of a part of the front end of the cot.

Referring to the parts by reference numerals, 10 represents the floor, and 10ft-10b the two sides of the ambulance body. Standards 12 and 13 are fixed to the ioor 10 and project upward therefrom.

14 represents a slide. This is a long narrow metal plate which is slidably supported on said standards so as to be slidable horizontally forward and backward in the ambulance body. Its edges ride on rollers 15, which are mounted on brackets 16 carried by said standards. Rollers 17, also mounted on said brackets engage the top surface of this slide and help to guide the same.

20 represents a horizontal guide bar which is connected at its front and rear ends with the posts 2l, 22. These are fixed to slide 14 near its ends.

23 represents a traveler which embraces and is slidable along the guide rod 20. The lower end of this traveler projects between vertical guide anges 14a secured to the top of the slide 14; and is equipped with rollers 23a which ride upon the slide 14. The traveler may, therefore, move forward and backward, but must retain its upright position. A cylindrical stud 23b is fixed to the upper end of the traveler and projects upward therefrom.

25 and 26 are horizontal transversely extended cot supporting bars. The middle part of the former is fixed to the post 21 and extends in both directions therefrom. The latter has a collar 27 fixed to it near its middle point. There is a cylindrical hole 27a drilled vertically through the downwardly extended lug 27b of this collar and i through the bar 26 and through the opposite side of the collar. The pivot stud 23b passes up through this hole; and the lug 27 b rests upon the traveler 23; and therefore this cot supporting bar 26 is swiveled to this traveler on a vertical axis, so that under circumstances to be presently described it may turn about this axis.

The cot frame, as shown, includes two side bars 39, a transversely extended bar 31 near the rear end of the frame, and two transversely extended bars 32, 33, near the front end of the cot frame.` Four legs 35 are secured to the side bars of the cot frame near their front and rear ends, and in position such that they may engage the two cot supporting bars 25 and 26. In the inner face of each of these legs 35 is a vertical groove 36, by which each leg is 4forked so that it may embrace one of the bars 25, 26. The ends ofthe bars 25, 26, projectinto these grooves 36 and engage the upper ends thereof,'and thereby the cot frame is supported and is prevented from moving sidew1se. v

When the cot is wholly inside of the ambulance body, the various parts mentioned are in the relative positions shown in Figs. 2.and 3. The slide 14 is now locked against rearward movement by a latch40, which is bar 25.

pivoted'to the rear standard 12 and engages a bracket plate 14 fixed to the slide. The front end of the cot is locked down on the bar 25 by bolts 41, which are slidably mounted on the legs and project into holes in the These bolts may be withdrawn by means of bell crank levers 42 which are pivoted to the cot frame; and each is provided with a handle 42a which lies just beneath and alongside of the adjacent cotframe handles 37. Each one of the sideI frame members of the cot terminates at both ends in one of these handles.

l/Vhen it is desired to remove the cot from the ambulance an attendant merely releases the latch L10 and then draws the slide 111 rearward, until it is stopped by the engagement of a bracket 14d fixed to said slide with the front standard 13. Then the attendant, taking hold of the two rear handles 37 and associated bolt withdrawing levers 42, first withdraws the bolts, and then lifts the rear end of the cot off of the rear bar 25. He then pulls the cot rearward. The traveler is thereby drawn. rearward until it engages with the post 21. lVhen the slide 14 and said traveler have moved as stated, the traveler will be wholly outside of the ambulance and in substantially the position indicated by dotted lines in Fig. 1. The attendant still holding the rear handles may now swing the cot about the vertical pivot stud 23b until the front handles of the cot are brought into such position that they may be easily reached by another attendant standing on the ground. This second attendant, by means of the adjacent levers 42, releases the bolts which connect the front end of the cot with the bar 26 and then lifts the cot free of said bar. rIo restore the cot to the ambulance the stated movements are caused to take place in the reverse order.

I-Iaving thus described my invention, what I claim is 1. In an ambulance, the combination of a slide movable horizontally forward and backward in said ambulance, two horizontal cot supporting bars carried by said slide and extended transversely with respect to the path of said slide,-the front bar being mounted to turn in a horizontal plane about a vertical axis, a cot having downwardly extended legs adjacent to its four corners, which legs have vertical grooves in their inner faces, which grooves receive the ends of said bars.

2. In an ambulance, the combination of a slide movable horizontally forward and backward in said ambulance, a horizontal transversely extended bar fixed to said slide for supporting the rear end of a cot, a traveler mounted on the slide and movable forward and backward thereon, a horizontal transversely extended bar for supporting the front end of the cot, which bar is pivoted on a vertical axis to said traveler, and a cot removably supported by the two cot supporting bars.

3. In an ambulance, the combination of a slide which is movable horizontally forward and backward in said ambulance, two posts fixed to said slide near its ends, a guide bar extending between and secured to said posts,

.a horizontal transversely extended cot supporting bar secured to the front post, a traveler having a sleeve which embraces and is slidable upon said guide bar, and which has wheels on its lower end to ride on said slide, a horizontal transversely extended cot supporting bar supported upon said traveler and connected therewith by a vertical pivot stud upon which said bar may turn, and a cot removably supported upon said two cot supporting bars. i

l. In an ambulance, the combination of a slide which is movable horizontally forward and backward in said ambulance, two posts fixed to said slide near its ends, a guide bar extending between and secured to said posts, a horizontal transversely extended cot supportingbar secured to the front post, a traveler having a sleeve which embraces and is slidable upon said guide bar, and which has wheels on its lower end to ride on said slide, a horizontal transversely extended cot supporting bar supported upon said traveler and connected therewith by a vertical pivot stud upon which said bar may turn, and a cot having handles at its ends and having also four downwardly extended forked legs adapted to engage said cot supporting bars, bolts carried by said legs for engaging said cot supporting bars, and bolt withdrawing levers carried b v the cot adjacent to the handles thereof for withdrawing said bolts.
